(efaq)Emacs does not display 8-bit characters
How do I make Emacs display 8-bit characters?
=============================================
Note:Single-byte Character Set Support.
On a Unix, when Emacs runs on a text-only terminal
display or is invoked with `emacs -nw', you typically need to use
`set-terminal-coding-system' to tell Emacs what the terminal can
display, even after setting the language environment; otherwise
non-ASCII characters will display as `?'. On other operating systems,
such as MS-DOS and MS-Windows, Emacs queries the OS about the character
set supported by the display, and sets up the required terminal coding
system automatically.
